It is with great sadness that we report the passing of our dear colleagues: Professor Helen Laburn and Professor Claus Jessen. We will always remember them.

Multi-scale process modeling is very appealing methodology for process optimization since it highlights certain issues that remain unexplored with conventional methodologies and debottlenecks certain potentialities that remain unexploited in chemical plants. In this work, a kinetic model with 2400 reactions and 140 species is implemented in a proper reactor network to characterize the thermal f...

John Trono published a new exercise in concurrent programming—the Santa Claus problem—and provided a solution based on semaphores [12]. His solution is incorrect because it assumes that a process released from waiting on a semaphore will necessarily be scheduled for execution. We give a simple solution in Ada 95 using higher order synchronization primitives: protected objects and rendezvous. We...

Tougher regulations for emissions reductions require refiners to achieve ever higher sulfur recovery efficiency in their Sulfur Recovery Units. A classic solution is to use an amine-based tail gas clean up unit (TGCU) behind a Claus plant. A U.S. refiner, working on a major capacity increase, evaluated and selected an alternate technology. They selected the SUPERCLAUS® Tail Gas Clean Up Process...

A Christmas season wouldn’t be complete without the annual complaint that the holiday has become too commercialized and that we need to put Christ back into Christmas, that he is the reason for the season. This gripe is not only misguided but has things backwards – Santa Claus is a better representative of the true spirit of Christmas than Jesus ever was or ever could be. As we will see, Christ...
